Declining cognitive abilities in older adults can contribute to significant changes in socioemotional health and substantially reduce their perception of well-being. Whereas much attention has been dedicated to creating cognitive training programs to improve cognitive health in old age, there is little emphasis on the consequences of such interventions for subjective mental functioning. We created a randomized controlled trial in which we evaluated the effects of an adaptive computerized cognitive flexibility training. Healthy older adults (60–80 years old) were assigned to one of three conditions (frequent or infrequent switching or active control group) and performed 58 half-hour sessions within a period of 12 weeks. We measured effects on subjective cognitive failures and executive dysfunctioning, everyday functioning, depressive symptoms, anxiety, and quality of life, before, and after training. Additionally, participants’ proxies rated their cognitive failures and executive dysfunctioning. Subjective cognitive failures and executive dysfunctioning improved 4 weeks posttraining in all groups, although effect sizes were low (?p2 = .058 and .079, respectively) and there were no differences between groups (all p’s > .38). No significant changes in subjective reports were seen directly after training, which was the case in all groups. Proxies did not report any functional changes over time, yet their evaluations were significantly more favorable than those of the participants, both pretraining (p < .0005) and posttraining (p = .004). Although we found no evidence of improvement on subjective mental functioning, we adduce several factors that encourage further research into the effects of computerized cognitive training on subjective performance. 相似文献

The literature on thought experiments has been mainly concernedwith thought experiments that are directed at a theory, be it in aconstructive or a destructive manner. This has led somephilosophers to argue that all thought experiments can beformulated as arguments. The aim of this paper is to drawattention to a type of thought experiment that is not directed ata theory, but fulfills a specific function within a theory. Suchthought experiments are referred to as functional thoughtexperiments, and they are routinely used in applied statistics. An example is given from frequentist statistics, where a thoughtexperiment is required to establish the probability space. It isconcluded that (a) not all thought experiments can be formulated asarguments, and (b) the role of thought experiments is more generaland more important to scientific reasoning than has previouslybeen recognized. 相似文献

People are likely to evaluate their group's standing on an ability dimension by comparing the performance level of their own group with that of an outgroup. However, in addition to contrasting performance outcomes, they may also compare the specific circumstances under which both groups have performed. From a related attributes perspective, we argue that the outcome of such a comparison is a crucial determinant of the extent to which the relative success or failure of one's group can be ascribed to its superior or inferior ability respectively, and hence of the degree to which the relative position of one's group on the performance dimension in question can be perceived as legitimate and stable (i.e. as justified and unlikely to change). Accordingly, the present research shows that information concerning performance‐related circumstances has an impact on a wide range of reactions to the relative performance of one's group, varying from the experience of positive and negative affect, to motivational responses such as changes in collective efficacy beliefs for performance improvement, individual effort on behalf of the ingroup, and the tendency to hinder the future performance of an outgroup.

The theoretical status of latent variables 总被引:1,自引:0,他引:1
This article examines the theoretical status of latent variables as used in modern test theory models. First, it is argued that a consistent interpretation of such models requires a realist ontology for latent variables. Second, the relation between latent variables and their indicators is discussed. It is maintained that this relation can be interpreted as a causal one but that in measurement models for interindividual differences the relation does not apply to the level of the individual person. To substantiate intraindividual causal conclusions, one must explicitly represent individual level processes in the measurement model. Several research strategies that may be useful in this respect are discussed, and a typology of constructs is proposed on the basis of this analysis. The need to link individual processes to latent variable models for interindividual differences is emphasized. 相似文献

The current study was aimed at (a) investigating the effect of three doses methylphenidate (MPH) and placebo on inhibition of a prepotent response, inhibition of an ongoing response, and interference control in Attention Deficit/Hyperactivity Disorder (AD/HD), and (b) studying dose-response relations for the three forms of response inhibition. To meet these aims, the following tasks were selected: two versions of the Stop Paradigm for inhibition of a prepotent response, a Circle Tracing Task and a recently developed Follow Task for inhibition of an ongoing response, and the Stroop Color-Word Test and an Eriksen Flanker Task for interference control. These tasks were administered to 23 boys with AD/HD during four treatment conditions: 5 mg MPH, 10 mg MPH, 20 mg MPH, and placebo. A pseudorandomized, multiple-blind, placebo-controlled, within-subject design was used. As hypothesized, inhibitory control in children with AD/HD improved under MPH compared to placebo. However, this effect was only significant for inhibition of a prepotent response and inhibition of an ongoing response (as measured by the Follow Task), but not for interference control. The relation between treatment condition and response was linear. However, this linear relation was due to improved inhibitory control under MPH compared to placebo, because no effects of MPH dose were observed for any of the response inhibition measures. 相似文献

Evart Van Dieren (1861-1940), a Dutch general practitioner who had a passionate aversion against psychoanalysis, wrote two particularly polemical books contra Freud but nevertheless did not succeed in generating much response. In this paper, some of his objections against psychoanalysis are briefly examined and compared with some present day arguments against Freud by Grünbaum and Crews, with the purpose of finding an answer to the question: What does it take to be a successful or unsuccessful critic? 相似文献

This research views dispositional inference as a process whereby perceivers integrate multiple inferences about a target person's motives and traits. The findings suggest that although perceived motives may stimulate extra attributional processing (S. Fein, 1996), the content of the inferred motive is important as well. Perceivers learned about situational forces implying that a target person had free choice, no choice, or an ulterior motive for helpful behavior. Inferences about the target's helpfulness differed depending on whether the target's behavior was attributed to an obedience motive (no-choice condition) or to a selfish motive (ulterior-motive condition). In general, inferences about motives were more predictive of dispositional inferences than were global causal attributions (to situational vs. dispositional forces) or base rate assumptions. 相似文献

Interactions in social life may be seriously affected by negative noise, whereby actual or perceived behavior is less cooperative than was intended (e.g., arriving late due to an unforeseen traffic jam). The present research examines whether negative noise exerts detrimental effects on impressions and cooperation and whether such effects could be reduced by communication. Consistent with hypotheses, Study 1 revealed that negative noise exerts detrimental effects on both impressions of partners' benign intent and cooperation and that these detrimental effects could be effectively reduced by communication about noise. Study 2 replicated both findings but only for individuals with low trust. Mediation analysis revealed that impressions of benign intent and prosocial interaction goals underlie the positive effects of communication on cooperation. 相似文献

In this essay, we explore the various aspects of hermeneutic relativity that have rarely been explicitly discussed. Our notion of “hermeneutic relativity” can be seen as an extension, with significant revisions, of Gadamer’s notion of Vorurteil. It refers to various choices and constraints of the interpreter, including beliefs concerning the best way of doing philosophy, what criteria are to be used to evaluate competing interpretations, and so on. The interpreter cannot completely eliminate the guidance and constraint originating from his/her “background.” However, in principle the interpreter can “choose” to be guided by other constraints. Hence, we speak of “choices” or “commitments.” Hermeneutic relativity is the major cause for the variation of competing interpretations. 相似文献
